Ceratosoma alleni from the Philippines

Hi,
I'd like to add another locale for Ceratosoma alleni... across the channel from Anilao. I've attached a photo. The animal was found in about 3 meters of water in front of Sabang Beach, Puerto Galera in the Philippines.

Locality: Sabang Bay, Puerto Galera, , 3 meters, Oriental Mindoro, Philippines, Pacific Ocean, 04 May 2006, sandy bottom below a floating bar. Length: 5 inches. Photographer: Stewart L. Sy.

Dear Stu,
Thanks for these beautiful photos. The one alongside shows how the large tubercles can bend in the current - much like a soft coral colony. I don't want to sound greedy, but what would be very interesting would be some photos of this species - or any species of tropical Ceratosoma - feeding on a sponge. At present we know almost nothing about the biology of these animals and it would be valuable to know whether they specialise on a particular family of sponges.
Best wishes,
Bill Rudman
